I'm doing weekly scans of a large excavation site. Every week they blast and haul off a bunch of rock. We overfly the site with a helicopter and use a SfM workflow to generate topography and a mesh. I would like to model the mesh's of the same area, but with the outer most mesh showing some transparency so that you can see the progression of the excavation. Is it possible to upload multiple meshes, and set different transparencies for each?
